CAPTCHA

Okay, CAPTCHAs are officially out of hand.

I just got a reCAPTCHA when I posted a WOT comment that included
this mathematical forumula:

βσ2t-1

Not only did it include Greek characters, the 2 should have been
a superscript and the t-1 a subscript. I had to use Microsoft Word
to get the beta and sigma to paste it in, as I don't have a Greek
keyboard.

The whole idea of reCAPTCHA is that only one of the images is
the test. The other is something in a literary source that OCR
software is having trouble identifying. Having people who solve
CAPTCHAs also help decipher those is useful to digitizing books,
especially works whose only hard copies are aging and at risk of
being lost. ("Stop spam. Read books.")

If you know which is which, you can enter anything you want for
the literary source image and still be able to get credit for
solving the entire CAPTCHA. It isn't really necessary to ask for
another, as the whole reason the second image is there is that
there is no right answer for it yet. But you're potentially
poisoning the statistics used for the OCR software. That's why I
did go to some trouble to provide an accurate answer. There's
examples of how it works here: http://www.google.com/recaptcha/digitizing

If they're going to give examples that use non-English
keyboards, they need to find a way to matching it with users using
those keyboards. Perhaps they used to and it's gone on the
fritz?

Not exactly. In fact, both are from books that couldn´t be read.
But one is identified, which means that you still can enter
something different, like change a letter, and it will work. The
other could be neglected. It´s pretty easy to see which one should
be entered.

Excuse my ignorance , but downloading an online Greek keyboard ,
could that have helped ?=== if only for a few characters == @ ARGΗ
= sorry for leaving with those" flowers " I never imagined , that
it would turn so ugly ===== very proud of the way you handled it
=== you are a great rater == sorry for going off topic for a moment
=

sorry I meant to say about "leaving you with roses " == I read
the posts , and I could not understand why OP would not listen ,
but that is life = b/w ARGH = do you think , that a key board in
Greek [ down loaded ] could have resolved the problem of using some
words to create a password ? thank you
